Firstly let's find hypotenuse(let it will be "n" of smaller triangle
Let use Pythagorean theorem
Now we need to find hypotenuse(x) of bigger triangle
The value of x must be rounded to 1 DP, so
Answer: x=24.1
Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same.The expressions which are equivalent to the given expression are,
Given information-
The expression given in the problem is,
<h3>Equivalent expression-</h3>
Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same.
For given expression,
As the above function is the function of <em>x. </em>Thus it can be written as,
<h3>Logarithm power rule</h3>
Logarithm power rule states that the exponent of the logarithm function can transfers to front of the logarithm and vice versa. Thus,
Now the value of is equal to the zero. Thus,
Hence the expressions which are equivalent to the given expression are,

Answer:
1) Distance=Speed*time
90=(x+1)*(x)+(2x+5)(x-1)
90=x^2+x+2x^2-2x+5x-5
3x^2+4x-95=0
2) 3x^2+4x-95=0. Using quadratic formula, we get
x=(-4±sqrt(16-4*3*(-95)<u>)</u>)/6, x=5 or - 19/5 but since x also represents time, it can't be negative.
3) Total time take she took for the journey is x+x-1=2x-1=2*5-1=9 hours
Answer: D
Step-by-step explanation:A scientist who studies the objects in the sky, including planets, galaxies, black holes, and stars, is called an astronomer
The range of the relation is 35,40,45,60,75
Reason being in relation range is the set of all second elements of ordered pairs (y-coordinates).
